SPECIFICATION forming part of Letters Patent No. 430,835, dated June 24, 1890.

Application filed April 2, 189d. Serial No. 846,283. (No model.)

To all whom it may concern.-

Be it known that we, CHARLES A. CODDING and LLOYD E. WVILBUR, of Dowagiac, in the county of Cass and State of lvlichigamhave invented a new and Improved Pan-Making Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved pan-making machine which is simple and durable in construction, very effective in operation, and specially designed to form ash-pans from the sheet-metal blanks.

The invention consists in certain parts and details and combinations of the same, as will be described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improvement partly opened and the core or block removed. Fig. 2 is a perspective view of the core or block. Fig. 3 is a perspective view of the blank. Fig. 4 is a perspective view of the improvement partly opened and with the core and blank in position, and Fig. 5 is a perspective view of the pan ready for turning the top for wiring and finishing.

The improved pan-making machine A is provided with a suitably-constructed frame B, forming on its upper end a table, on which are hinged side doors 0 D and end doors E F, adapted to be moved into a horizontal position, so as to be in line at their top surfaces with the top of the frame B. The said doors then rest on the cushioned brackets G, secured to the sides of the frame B, as is plainly shown in Figs. 1 and 4.

The side doors 0 and D are provided on their end edges with curved recesses O and O and D D respectively adapted to be en gaged by correspondingly-shaped plates H, H, H and H hinged on opposite sides to the end doors E and F, as is plainly shown in Figs. 1 and 4. Each of the said plates H, H, H and H is provided on its outer or under side with a handle H for conveniently turning the respective plate, as is hereinafter more fully described.

The upper or outer end of each door 0, D, E, or F is provided with a spring-catch 1, adapted to engage a staple J, secured at the sides near the upper end of a core or block K, the bottom of which is adapted to rest on the table formed on the top of the frame B. The sides of the core or block K are slightly inclined, according to the inclination intended to be given to the sides of the pan to be made. The doors 0, D, E, and F are adapted to swing up, so as to press the sheet metal against the said sides of the block, as hereinafter more fully described.

The blank L to be used for making a sheetmetal pan is provided with the flanges L, L L and L adapted to rest on top of the doors 0, D, E, and F, respectively, when the said doors are opened and extend in a horizontal position, resting on their brackets G. The end flanges L and L are also provided on their sides with short flanges L adapted to be bent by the plates H, 1-1, H and H so as to fold over the said flanges L and L as shown in Fig. 5.

The operation is as follows: WVhen the blank L has been prepared, the several doors are swung into a horizontal position, resting on the brackets G. The blank L is then placed on the table on top of the frame B, so that the flanges L, L L and L extend onto the doors 0, D, E, and F, respectively. The operator then places the core or block K onto the blank and then holds the block down by hand or a suitable device, after which one of the doors 0 or D is swung upward, carrying with it the respective side flange L or L so that the latter is pressed against the respective side of the core or block L. At the same time the spring-catch I engages its corresponding staple J on the block K, so as to lock the said door to the said core or block K. The other side is then operated in a similar manner, after which the two end doors E and F are likewise swung into an uppermost position to bend the end flanges L and L to the corresponding ends of the block K. When the several doors have been swung up and locked to the block K by their respective spring-catches I engaging the staples J, then the operator takes hold of the handles H of. i the several plates H, H, H and 1-1 and moves the handles toward the adjacent side 0 or 1), so that the flanges L of the end flanges L and L are bent into the cutout parts in the sides of the side doors 0 and D, whereby the side flanges L are passed onto the side flanges L and L When this has been accomplished, the several catches I are unlocked from the 'staples J, and the doors are then swung downward, the block K is removed, and the pan has been formed and is ready to be riveted by passing the rivets through corresponding apertures in the flanges L and the ends of the side flanges L and L as is plainly shown in Figs. 3 and 5. The pan is then ready for turning the top for wiring.

It will be seen that by this machine pans can be very quickly shaped ready to be riveted. It will further be seen that the machine is very simple in construction, and it requires very little power to operate the same by hand.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A panmaking machine comprising a frame B, the upper end of which forms a table, end doors D, hinged to the ends of the table and recessed at their ends, side doors E, hinged to the table and provided at their ends with hinged sections adapted to enter said recesses and each provided with an outward-extending ofiset handle H a separate and independent block or core K, adapted to the space between said doors, and fastenings for connecting the free or swinging edges of the four doors with the upper end of the block at its four sides, substantially as set forth.

2. In a pan-making machine, the combination, with a table, of Side doors hinged to the said table and having recessed ends, end doors hinged to the said table, plates hinged to the sides of the said end doors, springcatches held on each of the said doors, and a block provided with staples adapted to be engaged by the said latches, substantially as shown and described.
